“…In contrast to the visibility assessment from possible viewpoints on the ground, we argued that the cityscape changes caused by the deployment of solar applications could also have visual impacts on the occupants through windows. As a crucial element connecting the inner self to outside world, the window view has been playing a great role in urban life, including residential satisfaction (Kim et al, 2022), thermal comfort (Ko et al, 2020), work performance (Lottrup et al, 2015), occupant well-being (Elsadek et al, 2020), visual privacy (Zheng et al, 2021(Zheng et al, , 2022, and even financial values (Turan et al, 2021). Predictably, with a large number of PV modules widely spread over the rooftops and even building facades, the original fabric of the building envelope will be changed, potentially resulting in a negative impact on the window view quality of neighboring occupants.…”

As a major component of social acceptance, visual impact is often considered a significant constraint in solar applications. Visual impact assessment of solar applications, however, has been limited to pedestrians in previous studies. The extent to which PV systems can have visual impacts on occupants and whether it is necessary to include occupants in the measurement of visual impact remains uncertain. To fill this gap, we extended it from pedestrians to occupants and proposed a quantitative method to integrate pedestrians and occupants into a framework, combining the estimation of solar potential for the feasibility assessment of PV applications in a built environment. The concept is tested with a real case, located in Qingdao city, China, to present the technical flowchart for the feasibility assessment of solar PV deployments with the visual constraint. Building surfaces with qualified solar irradiation and low visibility were identified and compared in two cases, that is, with and without the inclusion of occupants as the visual constraint. The comparison results show that the change of suitable building surfaces for solar applications is 172,306 m2 (21% of suitable area) and 126 GWh (19% of yield energy) across the study area, indicating the significance of including occupants in the visibility assessment for the deployment of solar applications. The proposed method considers the visual constraint for the feasibility assessment of solar applications from the perspective of pedestrians and occupants, and it is helpful to identify the suitable surfaces for the large-scale deployment of solar applications at an early planning stage of solar city.

(1) Background: In the process of urbanization, current suburban village spaces are undergoing drastic changes. Many villages have lost their original rural appearances, and their unique rural cultures have been destroyed. (2) Methods: In this study, we used the Depthmap software to analyze the integration and comprehensibility of the village spaces in the central suburbs of Jilin province. Based on spatial syntax theory, we quantitatively interpreted the suburban village spaces, and we analyzed the correlations between their spatial morphological characteristics and industrial structures. (3) Results: Fishbone and radial villages each have one spatial nucleus, while comprehensive villages have multiple spatial nuclei. The comprehensibility of the villages with industrial structures that are dominated by the secondary and tertiary industries expressed higher results, with the highest comprehensibility value for the village of Nianshan (0.874). (4) Conclusions: The spatial characteristics of the suburban villages in central Jilin province generally have a high correlation with their industrial structures. We can use the spatial syntax measurement index as a basis for the spatial-form adjustment and reconstruction of the villages, with the aim of providing a reference for the industrial selection of suburban villages with different landforms and industrial structures, as well as the sustainable development of rural cultural tourism, in order to contribute to the revitalization of the countryside in the new era.
